[PATCH libXi] Fix XIScrollClass increment value on 32-bit machines

[Chase Douglas]

This fixes scroll class increment values on 32-bit machines. Performing
1UL << 32 shifts the bit off the end of a 32-bit unsigned long value. By
expanding to 1ULL, we have the full 64-bits of an unsigned long long
including on 32-bit machines.

Before this change, xinput list --long would output scroll increment
values of -nan.

This is likely the cause of bad scrolling behavior in GTK+ master.
